Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent water meters, and specifically relates to an Internet of Things intelligent water meter that is convenient to adjust. Background Art

[0002] In the prior art, in order to further ensure accurate billing, a filter is usually provided inside the water meter to intercept impurities in the water to prevent the impurities from jamming the billing mechanism and causing inaccurate water meter readings.

[0003] An intelligent water meter based on the Internet of Things and convenient to control water volume disclosed in Chinese invention patent CN113280880A is provided with a filter inside the water meter. The filter is located between the water inlet end and the counting end of the water meter to filter the water flow passing through the wheel disc.

[0004] However, the filter is set inside the water meter and is in a sealed state. After long-term use, it is difficult to remove the impurities on the filter, which easily causes the water flow to decrease, and it is very troublesome to clean the filter only by disassembling the water meter. Summary of the Invention

[0012] A sealing strip is laid on the upper surface of the notch of the expansion groove. The pressing plate is placed on the sealing strip. A convex platform is integrally connected to the center of the upper surface of the pressing plate. A hole for the pull rod to pass through is opened at the center of the convex platform. A slot is opened at the bottom of the convex platform. A plug is installed in the slot. A sealing ring is fitted in the middle of the convex platform. Both the plug and the sealing ring are sleeved on the pull rod.

[0013] A flap is rotatably connected to the upper port of the expansion groove by means of a spring hinge. The flap covers the pressing plate and the pull rod above.

[0014] An inlet cavity is opened inside the regulating valve, and the inlet pipe is communicated with the inlet cavity. A valve cavity is opened on the lower surface of the inlet cavity. The valve cavity is of a conical structure. A flowing water channel is opened on the lower surface of the valve cavity inside the regulating valve, and the flowing water channel is communicated with the accommodation cavity.

[0015] A valve cover is connected to the upper surface of the regulating valve by means of bolts. A sleeve is provided at the center of the upper surface of the valve cover. A screw sleeve is connected to the upper surface of the sleeve. A conical structure valve core is provided inside the valve cavity. A first screw rod is connected to the upper surface of the valve core, and the first screw rod is threadedly connected with the screw sleeve. A spring is sleeved on the first screw rod.

[0016] A connecting pipe is provided on the side of the flowmeter and is communicated with the accommodation cavity, and the connecting pipe is far away from the outlet pipe. An impeller is connected to the center inside the flowmeter by means of a rotating shaft. The end of the rotating shaft penetrates through the flowmeter and is connected to the intelligent counter.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) The filter frame of the present invention can filter impurities in water. The height of the filter frame is less than the height of the accommodating cavity, which provides a certain space for the storage of impurities, ensures that the water entering the subsequent components of the water meter is relatively clean, reduces the damage of impurities to other components of the water meter such as the flow meter, and improves the service life of the water meter. The design of the scraper makes it easier to clean the impurities in the filter frame. The outer wall of the scraper fits the inner surface of the filter frame and can effectively scrape off the impurities attached to the inner wall of the filter frame. The scraper can be taken out by simple operation, which is convenient for processing the impurities collected on the scraper.

[0018] (2) The present invention can clean the inside of the water meter without cutting off the water flow. The pull rod drives the scraper to move upward in the filter frame to scrape off and collect impurities inside the filter frame. Then, the movable plate is pushed to block the space below the accommodating cavity, and the scraper is taken out to complete the cleaning operation. This avoids the inconvenience caused by the traditional cleaning method that requires cutting off the water flow, and ensures continuous water supply.

[0019] (3) The movable plate of the present invention is slidably connected in the board bin, and its two sides slide in the embedded grooves, which ensures the stability of the movable plate's movement. The first baffle at the front end of the movable plate and the second baffle at the rear end, as well as the cooperation with the clearance groove and the baffle bar, enable the movable plate to achieve good sealing and positioning effects at different positions.

Detailed implementation manners

[0032] To make the above objects, features and advantages of the present invention more apparent and understandable, the following detailed description of the specific implementation manners of the present invention will be made with reference to the accompanying drawings of the specification.

[0033] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0035] Refer to Figures 1 - 3This is a structural diagram of an Internet of Things intelligent water meter that is easy to adjust in this embodiment. The intelligent water meter in this embodiment includes a regulating valve 1, which adjusts the water flow rate entering the water meter. A filter 2 is connected to the side of the regulating valve 1. A flow meter 4 is assembled on the front surface of the filter 2. An inlet pipe 111 is also provided on the side of the regulating valve 1, and an outlet pipe 42 is provided on the flow meter 4. Refer to Figure 6 , a receiving cavity 21 is formed in the filter 2, and the receiving cavity 21 is internally connected to the regulating valve 1 and the flow meter 4 respectively. A filter frame 23 is disposed in the receiving cavity 21. The receiving cavity 21 connects the regulating valve 1, the filter frame 23, and the flow meter 4, enabling the water flow to smoothly circulate among these components. At the same time, it provides an installation space for the filter frame 23 to achieve the filtering function, and the filter frame 23 filters the incoming water flow, intercepting impurities in the water to prevent impurities from entering the flow meter 4 of the water meter, thereby protecting the normal operation of the flow meter 4. Refer to Figure 7 , the height of the filter frame 23 is less than the height of the receiving cavity 21, which provides a certain space for the storage of impurities, ensuring that the water entering the subsequent components of the water meter is relatively clean. A plate bin 3 is installed on the outer surface of the side of the filter 2 opposite to the regulating valve 1. A movable plate 31 is slidably connected in the plate bin 3. The movable plate 31 plays a role in blocking the space below the receiving cavity 21 during the cleaning process. At the same time, during normal operation, its fixed position and sealing design help to maintain the water flow state inside the receiving cavity 21 and prevent water leakage. Refer to Figure 8 and Figure 10 , a scraping disc 241 is movably provided at the bottom of the filter frame 23. A pull rod 24 is connected to the center of the upper surface of the scraping disc 241 by a bearing. The pull rod 24 serves as a transmission component for the movement of the scraping disc 241, connecting the scraping disc 241 to the outside, enabling external operations to be transmitted to the scraping disc 241, driving the scraping disc 241 to move up and down in the filter frame 23. The scraping disc 241 is used to scrape off the impurities inside the filter frame 23. Its outer wall fits the inner surface of the filter frame 23 and moves up and down in the filter frame 23 driven by the pull rod 24, scraping off and collecting the impurities on the inner wall of the filter frame 23. Refer to Figure 9 , an expansion slot 5 is formed on the upper surface of the filter 2, and the expansion slot 5 is communicated with the upper end of the receiving cavity 21. A pressing plate 26 is fixedly connected in the expansion slot 5 by screws. The pull rod 24 passes through the pressing plate 26 and extends to the outside. The expansion slot 5 provides an installation position for the pressing plate 26, and the end of the pull rod 24 is lower than the notch of the expansion slot 5. A flap 25 is rotatably connected to the upper port of the expansion slot 5 by a spring hinge. The flap 25 covers the pressing plate 26 and the pull rod 24 above, hiding the pressing plate 26 and the pull rod 24 through the flap 25 to achieve an aesthetic effect.

[0036] In this embodiment, water flows into the regulating valve 1 from the water inlet pipe 111. The regulating valve 1 can control the water flow rate entering the accommodation chamber 21 according to the set flow rate requirement. After the water entering the accommodation chamber 21 is filtered by the filter frame 23, impurities are intercepted in the filter frame 23, and the clean water enters the flow meter 4 for water volume measurement. When cleaning is required, the pull rod 24 is used to drive the scraping plate 241 to move upward in the filter frame 23 to scrape and collect the impurities inside the filter frame 23. When the scraping plate 241 moves above the filter frame 23, it pushes the movable plate 31 to move into the accommodation chamber 21 to block the space below the accommodation chamber 21. Then, the pressing plate 26 is removed and the scraping plate 241 is taken out, so as to clean the water meter without intercepting the flow.

[0037] Refer to Figure 9 , a relief groove is centrally formed in the inner wall of the accommodation chamber 21 close to the side of the plate bin 3, and the relief groove extends outward through the outer wall of the filter 2. The relief groove is located above the filter frame 23. The upper surface of the movable plate 31 is provided with ribs 313. When the movable plate 31 moves into the accommodation chamber 21, the ribs 313 slide in the relief groove. In this embodiment, the cooperation of the relief groove and the ribs 313 provides guidance and limitation for the movement of the movable plate 31. The cooperation of the relief groove and the ribs 313 plays a guiding role in the movement of the movable plate 31 on the one hand, preventing the movable plate 31 from shaking when moving in the plate bin 3 because the thickness of the movable plate 31 is less than the height of the cavity of the plate bin 3, so that the movable plate 31 can accurately block the space below the accommodation chamber 21, and at the same time preventing the movable plate 31 from shifting during the movement. At the same time, a slot for the ribs 313 to pass through is provided in the upper part of the corresponding cavity of the plate bin 3.

[0038] Refer to Figure 9 and Figure 11 , an embedding groove 22 is also formed in the inner wall of the accommodation chamber 21 where the embedding groove 22 is formed. The front end of the movable plate 31 is provided with a first blocking piece 311. The embedding groove 22 cooperates with the first blocking piece 311 of the movable plate 31. When the movable plate 31 is located in the plate bin 3, the first blocking piece 311 can be embedded in the embedding groove 22. The thickness of the first blocking piece 311 is equal to the depth of the embedding groove 22, so that the first blocking piece 311 will not protrude into the accommodation chamber 21 and affect the rising of the scraping plate 241. A silica gel sheet is attached to the rear surface of the first blocking piece 311. When the movable plate 31 is located in the plate bin 3, its first blocking piece 311 is embedded in the embedding groove 22, and the silica gel sheet of the first blocking piece 311 is closely attached to the embedding groove 22, which helps to achieve the sealing function and prevent water from leaking from the connection between the movable plate 31 and the accommodation chamber 21.

[0039] Refer to Figure 7 and Figure 8, a cavity is provided inside the board bin 3 for the movable board 31 to be placed in, enabling the movable board 31 to slide inside the board bin 3, and the thickness of the movable board 31 is less than the height of the cavity of the board bin 3. A second stop piece 312 that fits the cavity is provided at the end of the movable board 31. The thickness of the movable board 31 being less than the height of the cavity of the board bin 3 reserves enough space for the movement of the second stop piece 312. A stop bar 33 is provided inside the cavity of the board bin 3. When the movable board 31 moves into the accommodation cavity 21, the second stop piece 312 fits tightly with the stop bar 33. The stop bar 33 serves to limit the movement position of the movable board 31 and also helps with sealing to prevent water from leaking through the gap between the movable board 31 and the board bin 3.

[0040] Refer to Figure 7 and Figure 8 , a sleeve holder 32 is provided at the center of the outer surface of the board bin 3. A second screw rod 321 is connected to the sleeve holder 32 by internal threads. The sleeve holder 32 provides an installation position for the second screw rod 321, enabling the second screw rod 321 to be stably installed at the center of the outer surface of the board bin 3 and providing support for the rotation of the second screw rod 321. The front end of the second screw rod 321 is connected to the end of the movable board 31 by a bearing. The second screw rod 321 serves as a power component for pushing the movable board 31 to move. By being connected to the sleeve holder 32 by internal threads, when the second screw rod 321 is rotated, its front end is connected to the end of the movable board 31 by a bearing, and the rotational motion can be converted into a linear motion to push the movable board 31 to move inside the board bin 3 and into the accommodation cavity 21.

[0041] Refer to Figure 3 and Figure 4 , a sealing strip 27 is laid on the upper surface of the notch of the expansion slot 5 to provide a sealing foundation for the pressing plate 26. When the pressing plate 26 is placed on the sealing strip 27, it can prevent water from leaking from the expansion slot 5, ensuring the sealing between the expansion slot 5 and the outside. A boss 261 is integrally connected to the center of the upper surface of the pressing plate 26, providing a structural foundation for the installation and sealing of the pull rod 24. A hole for the pull rod 24 to pass through is provided at the center of the boss 261. A groove is provided at the bottom of the boss 261, and a plug 2612 is installed in the groove to prevent water from entering the expansion slot 5 through the groove at the bottom of the boss 261, enhancing the sealing performance around the pull rod 24. A sealing ring 2611 is fitted in the middle of the boss 261 to further enhance the sealing performance around the pull rod 24. Acting together with the plug 2612, it ensures the sealing performance at the expansion slot 5. Both the plug 2612 and the sealing ring 2611 are sleeved on the pull rod 24 to achieve the fixation, sealing, and limiting of the pull rod 24.

[0042] Refer to Figure 3A water inlet chamber 11 is provided in the regulating valve 1, and a water inlet pipe 111 is connected to the water inlet chamber 11. A valve chamber 112 is provided on the lower surface of the water inlet chamber 11, and the valve chamber 112 is a conical structure. A water flow channel 113 is provided in the regulating valve 1 and on the lower surface of the valve chamber 112, and the water flow channel 113 is connected to the accommodating chamber 21.

[0043] In summary: the sealing of the movable plate 31 during its movement in the plate bin 3 and the accommodating chamber 21 is achieved through the coordinated cooperation of multiple components. The cooperation between the first baffle 311, the clearance groove and the silicone sheet, and the cooperation between the second baffle 312 and the baffle 33 ensure the sealing of the movable plate 31 in different states from different positions and angles. At the same time, the cooperation of the sealing strip 27, the boss 261, the plug 2612 and the sealing ring 2611 at the expansion groove 5 also ensures the sealing of the entire water meter in this area to prevent water leakage. The movement of the movable plate 31 is precisely controlled by the second screw 321 in the sleeve 32. Under normal working conditions, the movable plate 31 is located in the plate bin 3, the first baffle 311 is embedded in the clearance groove, and the silicone sheet is close to the clearance groove to achieve sealing. When the filter frame 23 needs to be cleaned, the filter frame 23 is cleaned by scraping. After the disk 241 moves upward to the top of the filter frame 23, the second screw 321 in the sleeve 32 on the outer surface of the rotating plate bin 3 is rotated. Since the second screw 321 is connected to the end of the movable plate 31 through a bearing, the rotational movement of the second screw 321 is converted into the linear movement of the movable plate 31. The movable plate 31 is guided by the ribs 313 and the give way groove in the cavity of the plate bin 3 and moves into the accommodating chamber 21 to complete the sealing. When the movable plate 31 moves to the inside of the accommodating chamber 21, the second baffle 312 fits tightly with the baffle 33, successfully blocking the space below the accommodating chamber 21. At the expansion groove 5, the pressure plate 26 is placed on the sealing strip 27, and the pull rod 24 passes through the hole in the center of the boss 261. The plug 2612 at the bottom of the boss 261 and the sealing ring 2611 in the middle are sleeved with the pull rod 24, ensuring the sealing around the pull rod 24 and preventing water from leaking from the expansion groove 5. In the whole process, various components cooperate with each other to jointly realize the normal operation, cleaning and maintenance, and sealing functions of the water meter.

[0044] See also Figure 6The upper surface of the regulating valve 1 is connected with a valve cover 13 by bolts, which plays the role of closing the internal structure of the regulating valve 1, and a sleeve 12 is provided at the center of the upper surface of the valve cover 13, and a screw sleeve 124 is connected to the upper surface of the sleeve 12. In this embodiment, the sleeve 12 provides an installation position for the screw sleeve 124. The sleeve 12 serves as an intermediate structure to connect the valve cover 13 and the screw sleeve 124, so that the screw sleeve 124 can be stably installed on the upper structure of the regulating valve 1. A valve core 123 with a conical structure is provided in the valve cavity 112, and a first screw rod 121 is connected to the upper surface of the valve core 123, and the first screw rod 121 is connected to the upper surface of the valve core 123. 21 is threadedly connected with the screw sleeve 124. In this embodiment, the screw sleeve 124 is threadedly connected with the first screw 121 on the valve core 123. By rotating the screw sleeve 124, the first screw 121 can be moved up and down, thereby driving the valve core 123 to move up and down in the valve cavity 112 to achieve regulation of the water flow rate. The valve core 123 is a key component of the regulating valve 1. The valve core 123 is located in the valve cavity 112 and has a conical structure. When the valve core 123 moves up and down in the valve cavity 112, the cross-sectional area of ​​the water flow channel in the valve cavity 112 is changed, thereby adjusting the water flow rate entering from the water inlet pipe 111.

[0045] See also Figure 7 It is worth noting that: in this embodiment, threads are only provided on a part of the first screw rod 121. The reason is that the sleeve 12 has a built-in sealing component for preventing water from entering the upper end of the sleeve 12. The sealing component is a part that can be adapted to the sleeve 12 in the prior art. The first screw rod 121 needs to pass through the sealing component and be threadedly connected with the screw sleeve 124. Therefore, it is sufficient to provide threads on the upper half of the first screw rod 121. If threads are provided on the first screw rod 121, the connection between the first screw rod 121 and the sealing component will cause greater wear due to the movement of the threads, thereby causing the sealing component to lose its sealing effect. Therefore, the first screw rod 121 is not required to be threaded. The contact portion between the rod 121 and the sealing assembly should be smooth, but as the first screw 121 rises, when a smooth section of the screw 121 enters the screw sleeve 124, the first screw 121 will not be able to have an effective connection with the screw sleeve 124, causing the first screw 121 to shake. Therefore, in this embodiment, a spring 122 is sleeved on the first screw 121, and the upper end of the spring 122 contacts the lower surface of the screw sleeve 124. The rebound force of the spring 122 causes the first screw 121 to always have a tendency to move downward, thereby ensuring that the valve core 123 remains concentric with the valve cavity 112 and continues to play a role in changing the cross-sectional area of ​​the water flow channel in the valve cavity 112.

[0046] See also Figure 5, a connecting pipe 41 is provided on the side of the flowmeter 4 and is communicated with the accommodating cavity 21, so that the water flow filtered by the filter frame 23 can enter the flowmeter 4, providing a measurement object for the flowmeter 4 to ensure accurate measurement of the water volume passing through the water meter. And the connecting pipe 41 is far away from the water outlet pipe 42. An impeller 43 is connected to the inner center of the flowmeter 4 by a rotating shaft. When the water flow enters the flowmeter 4 through the connecting pipe 41, the impact force of the water flow will cause the impeller 43 to rotate. The rotation speed of the impeller 43 is proportional to the water flow rate. The end of the rotating shaft penetrates through the flowmeter 4 and is connected to the intelligent counter 44. The intelligent counter 44 can receive the signal generated by the rotation of the impeller 43 and convert it into readable water volume data to achieve accurate measurement of the water volume passing through the water meter. In this embodiment, in the regulating valve 1, when it is necessary to adjust the water flow rate, rotate the screw sleeve 124. Since the screw sleeve 124 is threadedly connected to the first screw 121, the rotation of the screw sleeve 124 will cause the first screw 121 to drive the valve core 123 to move up and down in the valve cavity 112. Since the valve core 123 is a conical structure, the cross-sectional area of the water flow channel in the valve cavity 112 will change when it moves up and down in the valve cavity 112. When the valve core 123 moves downward, the cross-sectional area of the water flow channel in the valve cavity 112 decreases, and the water flow rate decreases; when the valve core 123 moves upward, the cross-sectional area of the water flow channel in the valve cavity 112 increases, and the water flow rate increases. The water flow after adjusting the flow rate by the regulating valve 1 enters the accommodating cavity 21, is filtered by the filter frame 23, and then enters the flowmeter 4 through the connecting pipe 41. In the flowmeter 4, the water flow impacts the impeller 43 to make it rotate, and the end of the rotating shaft of the impeller 43 is connected to the intelligent counter 44. The rotation speed of the impeller 43 is proportional to the water flow rate, and the intelligent counter 44 counts according to the rotation of the impeller 43, thereby converting the rotation of the impeller 43 into readable water volume data to achieve the measurement of the water flow rate.
